CVE-2009-1046 Information

Description

The console selection feature in the Linux kernel 2.6.28 before 2.6.28.4 2.6.25 and possibly earlier versions when the UTF-8 console is used allows physically proximate attackers to cause a denial of service (memory corruption) by selecting a small number of 3-byte UTF-8 characters which triggers an \off-by-two memory error.\ NOTE: it is not clear whether this issue crosses privilege boundaries.
